- `NgHost` to `CompilerHost`
- `AotCompilerHost.resolveFileToImport` to `AotCompilerHost.fileNameToModuleName`
- `AotCompilerHoset.resolveImportToFile` to `AotCompilerHost.moduleNameToFileName`
Refactored ReflectorHost to allow it to be tested.
Fixed an issue where the .d.ts was findable but it wasn't used by the project
(This happens when the .metadata.json file references a module that was not
needed, such as it doesn't declare any types, and the reference to it was
elided by TypeScript when writing the .d.ts file).
Added tests for ReflectorHost
